Spyderco Bench Stone Sharpener (Medium) 302M

The Spyderco 302M is a medium grit bench stone that measures 2″ x 8″ x 1/5″ and comes in a rigid polymer storage case complete with non-skid rubber feet for tabletop use. As with all of Spyderco’s ceramic stones, use our benchstones dry without lubricants or oils. To clean: wash with fresh water and scrub metal particles from the stones with a plastic scouring pad and abrasive powered cleanser.

Because Spyderco’s bench stones are flat and broad they are highly effective for honing wide tools like plane irons, chisels, large blades, woodworking equipment, even ski edges.
